SumUp Reviews in October 2026: User Ratings, Pros & Cons

Reported to the Trading Standards for Fraudulent Payments

I had ordered a SumUp card reader for an event. Initially, all was well and I was satisfied with the purchase. They had a free trial for their SumUp One, which had to be cancelled in 7 days. I signed up, used the benefits and cancelled PRIOR to the 7 days. Fast forward to today and I have subsequently been charged 2x SumUp One invoices for no use of the service. Their own subscriptions page admits I have no subscription with them, but it persists. They have not responded to emails and I ...

Stay Away from this Service! Be safe

Here's the corrected version of your text: The first call to customer service lasted 2 hours, only for them to tell me that we needed to buy more equipment to complete the installation. That was my main concern. Then, when I called to inform them that I wanted to return the equipment, the customer service representative told me it wasn't possible and that I'm stuck with it for 12 months with no option for returns. It's funny because the salesman who visited us said we could try it ...

SumUp user of 8ish years!

We’ve used SumUp for our skincare business for about 8 years and we love them! When we started trading we were only doing occasional ‘in person’ events and a number of other card payment options charged monthly which wouldn’t work for us. Good rates, easy to use app, prompt payments and the machine is a good size and robust enough to carry around- we’ve got 3 air card readers now for those days we have multiple events. Only had to contact customer services a couple of times- once when we ...

This has been the worst experience - STAY AWAY FROM SUM UP

This has been the worst experience. I purchased the Sum Up Solo card reader back in September, to use for my catering business. I had an event and used the machine. The next day I received an email asking for all these details regarding my business, such as invoice, social media presence etc. I provided all these details. A few days later, I received an email saying that they have closed my account and i can either have the money returned to the customers or wait 2 months for the funds to ...

Had a SumUp 3G machine for about 2…

Had a SumUp 3G machine for about 2 years, only ever switched it on once. Now the card reader won't charge and when you switch it on, I'm told the device has been blocked. Waste of money, waste of time. No thanks SumUp. Your booby trapped devices stink... ------------------------------------------------------------ Update: SumUp did contact me and basically told me TOUGH - buy another! I think not.................

Unreliable - lost hundreds of pounds

As a frequent taxi customer, I have lost hundreds of pounds because of SumUp. Drivers who use this are increasingly insistent that the receipt is sent to my email but even if the email does arrive, many are unusable for expense claims. I always ask the driver to write a receipt but some (especially Aberdeen) say "If you pay with paper then the receipt is paper"!!
